The groove of oil pocket side wall flows to low-pressure side from high-pressure side, when having stronger stickiness, and the size of groove in itself due to hydraulic oil
It is limited, so the side wall of knob can not be bonded with the side wall of oil pocket, so that moment of torsion is directly transmitted, with this so that outer shroud has at once
There is buffer time.And when starter stops operating, driving wheel will under the action of return spring return.
In the present solution, although return spring take part in buffering course, but return spring will not be subject to too big power, it is only necessary to
The power for being enough to make driving wheel return is provided；After hydraulic oil completes buffering, the side wall of driving wheel knob is by the side wall with oil pocket
Fitting, so as to transmit moment of torsion, in the process, no component can be subject to large impact and be destroyed, and hydraulic oil also has lubrication
Effect, so this buffer unit be without often repairing, and compared to other buffer units, last a long time.
Preferred solution one, as the further optimization to base case, the oil pocket is provided with six altogether；Oil pocket is set
For six, knob also can equally increase as six, since knob not only has the function that buffering, also have the work for transmitting moment of torsion
With, therefore the quantity increase of knob, be conducive to improve its intensity, avoid knob from fractureing；But the sky of the excessive oil pocket of quantity of knob
Between will reduce accordingly, then buffer distance will diminish；Therefore oil pocket is arranged to six, sliding tooth is met that intensity will
Ask, while can also meet buffer distance.
